Specification of Letters Patent.

Patented J an. 30, 1906.

Application filed December 4,1903. Serial No. 188,825.

To all whom it may concern:

Be it known that I, GUSTAV GOLDMAN, of Baltimore, Maryland, have invented a new and useful Process of Making Fabric Containing Haircloth, which process is fully set forth in the following specification.

The present invention relates to the manufacture of a fibrous fabric having a layer of haircloth incorporated therein. In an application of even date herewith, Serial No. 183,823,I haveclaimed a product of this kind, and in still another application of even date herewith, Serial No. 183 ,8 24;, I have de-' scribed and broadly claimed a generic process for making said product, as well as one species under said generic process.

The present application relates to a spe cific process for making the product referred to, which specific process is disclosed but not claimed in said last-mentioned application.

The process of the present invention conof haircloth having a more or less open mesh in contact with a layer of fibers, such as wool or mixtures containing Wool which are suitable for felting, so'that the fibers will project to a greater or less extent through the meshes of the haircloth, and then by the ordinary or any suitable felting operation incorporating the haircloth with the fibrous layer. Usually the haircloth is interposed between two layers of fibers, so that the fibers will project through the meshes of the cloth from both sides thereof, and these fibers are caused to interlock by the felting action, usually in the presence of a suitable binder, as soap, and a fixing solution, as alum solution, so that the haircloth is securely incorporated in a coherent mass of fibers. For some uses the employment of a single layer of fibers is preferred, while for others a plurality of fibrous layers is best; but whether one layer or two is or are employed the process remains substantially the same-viz. the haircloth is secured in position with relation to the fibrous mass by the felting action of fibers which project through the meshes of the cloth. Y

The specific method Which is preferred in layer of suitable fibers, as Wool, superiinposin thereon a layer of haircloth having a mes sufiiciently open to perm't the fibers to pass therethrough, and then, if a plurality of fibrous layers is to be employed, placing a layer of fibers upon the haircloth, after which the whole is rubbed in the presence of a suitable binder, as soda soap, then passing the rubbed fibers with the soap therein through a 'solution of alum to fix the soap and render it waterproof, after which the fabric is rubbed in a flat form in the presence of heat and pressure. This produces a felted mass of fibers with the haircloth incorporated therein either near the surface or well within the body of the fibrous mass, depending upon whether a single or a plurality of fibrous layers were employed in the operation.

Having thus described the invention, what is claimed is 1; The process of making a fibrous material with avlayer of haircloth incorporated therein, which consists in placing a sheet of haircloth in contact with a layer of fibers so meshes of the haircloth, then felting the fibers ill the presence of a suitable binder, and then passingthrough a fixing solution.
